1. Immune System Missions

Key Concepts & Definitions

  • Immune system: The set of cellular and molecular mechanisms that protect the organism and support its survival in its environment.

★ Must-know

  • The immune system has four major missions:
    • Protect the organism from aggression
    • Avoid attacking the organism and beneficial components through immune tolerance
    • Contribute to tissue repair
    • Protect against a later attack through immune memory

Further detail

  • The intestinal microbiota can be beneficial because it produces vitamins and its loss can increase the risk of chronic disease.

Memory Hook

Protect, tolerate, repair, remember: PTRM

2. Sources of Aggression

★ Must-know

  • External aggressors include:
    • Infectious agents
    • Toxins
    • Trauma

Further detail

  • Infectious agents include:
    • Viruses
    • Bacteria
    • Parasites

Memory Hook

External aggressors enter from outside, whereas internal aggressors arise within the organism
